Commit message: xkb: ProcXkbSetDeviceInfo should work on all attached SDs.

If called with XkbUseCoreKbd, run through all attached SDs and replicate the
call. This way, we keep the SDs in sync with the MD as long as core clients
control the MDs.
CVE: CVE-2022-2320
Vulnerability description: A flaw was found in the Xorg-x11-server. The specific flaw exists within the handling of ProcXkbSetDeviceInfo requests. The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer. This flaw allows an attacker to escalate privileges and execute arbitrary code in the context of root.
